Like predation and competition, recognition of mutualisms' functional responses and consumer-resource interactions provides new insights into their density-dependent population dynamics. Fluctuations ...

If causes of population fluctuation vary temporally, then tests that search for density dependence in long time series cannot distinguish, at any given time, how much population change is due to ...

Many host-parasite models assume that transmission increases linearly with host population density ('density-dependent transmission'), but various alternative transmission functions have been proposed ...
